Working a bamboo/purpleheart/osage/walnut composite. I needed to leave more belly and or length, if it'll be walnut.
Oh, and if this was about my personal anatomy, the belly failure already occurred. :)
-
Oh well lesson learned move on to another one. The bow looks short and to heavy to make an even bend.
-
The limbs look pretty thick to bend much. Perhaps, you forced it. Jawge
-
Maybe it's not as thick as it looks. It was pulling 40# at 20" when I noticed fatal flaws.
-
If you try it again, use the osage for the belly and walnut for the core. Osage is much stronger and way more elastic.
-
You've got to be gentle, gentle when using walnut for a belly. It's very soft and not very dense the best backing for it is ash imo.
-
Lots going wrong there...put the walnut in the core n osage on the belly...IF you just have to have walnut as a belly use maple,ash etc(one of the lesser overpowering Whitewood's for backing),and then you have to go longer and much much wider than what you have....trying to use walnut as a belly in lam bows is a waste of time n materials IMO....I'd grind off the walnut n glue on some osage to save that if that's what ya wanna do
-
Walnt belly, bamboo back and a thick cross section is asking a lot of walnut. The only good walnut bows I have made were hickory backed or self bows and 2.25" wide or so.

That's a shame, looks like a lot of work went into that. I get upset if I take too much off of a self-bow stave and it lowers the draw weight.
I couldn't imagine the work that went into cleaning up those ply's and glue-up. Maybe you could salvage the handle and glue it in-between some full-length boards/plys...... bamboo flooring?
